I would be remiss not to agree with the message of this discussion. As an art teacher, this is an ongoing obstacle in student education. Most students will walk into art with the mindset that they will not succeed as a default. Creating a classroom environment that understands that I will always provide all of the tools needed to be successful, is important to me. To the extent that it is a phrase that I will repeat at the beginning of every project, whenever we introduce a new skill or a new art material.
